Definitions

  • the foraminous material generally may be any electrically non-conductive, porous, sheet or web such as woven or non-woven fabrics, papers or other mesh of monofilament or yarn-like fibers.
  • Foraminous or mesh materials useful as reinforcement within the photohardenable layer include cotton and other fabrics made from naturally occurring fibers, synthetic fabrics such as nylon, polyarylamids, polyesters, e.g., polyethylene terephthalate, polypropylene and the like, and woven fiber glass, papers, e.g., filter paper or other such non-woven materials made from the aforementioned fibers.
  • the reinforced, adherent, photohardenable sheet may be manufactured by any conventional or convenient way.
  • Suitable monomers which can be used as the sole monomer or in combination with others include the following: t-butyl acrylate, 1,5 -pentanediol diacrylate, N,N-diethylaminoethyl acrylate, ethylene glycol diacrylate, 1,4-butanediol diacrylate, diethylene glycol diacrylate, hexamethylene glycol diacrylate, 1,3-propanediol diacrylate, decamethylene glycol diacrylate, decamethylene glycol dimethacrylate, 1,4-cyclohexanediol diacrylate, 2,2-dimethylol propane diacrylate, glycerol diacrylate, tripropylene glycol diacrylate, glycerol triacrylate, trimethylolpropane triacrylate, pentaerythritol triacrylate, 2,2-di(p-hydroxyphenyl)-propane diacrylate, pentaerythritol tetra
  • the removable support is removed from each side of the imaged reinforced photopolymer sheet and copper powder is dusted onto the surfaces and into the through-holes. After removing excess copper powder, each surface is uniformly exposed for 3 minutes to the exposure source described in Example 1.
  • the reinforced sheet with catalyzed patterns and holes is immersed in an electroless plating solution described in Example 1. Within one hour, a conductive pattern is obtained on both sides of the sheet and in the through-holes so that circuit patterns are conductive from one side of the sheet to the other side through plated through-holes.
  • the two-sided printed circuit board is baked for 1 hour at 160° C.
